MONEY-CHANGING MACHINE.

To all whom 'it m ay concern f Be it known that I, BERNARD H. CAMDEN, a citizen of the United States, residing at Parkersburg, Wood county, and State of West Virginia, have invented and discovered certain new and useful Improvements in Money-Changing Machines, of which the following is a specification.

My said invention relates to machines for making change, particularly to machines adapted for automatically selecting coins that will aggregate the change required when the amount of the purchase and the amount of money tendered in payment are known, the machine being also adapted for 'throwing out any given amount in change up to a fixed maximum, and it consists in various improvements in the construction and arrangement of the parts, whereby such av machine is provided of a comparatively simple and inexpensive construction and one thatis noi:l only reliable and accurate in its opera-tion, but not likely to. get out of order, all as will be hereinafter more fully described and claimed. 4 i

Referring to the accompanying drawings which are made a part hereof and on which similar reference charactersl indicate similar parts, Figure 1 is a top or plan view of a money changing machine of my improved construction, Fig. 2 a horizontal section, as seen when looking downwardly from the dotted lino 2-2 in F ig. 3, Fig. 3 a vertical section, as seen when looking in the direction indicated by the` arrow from the dotted line 3 3 in Fig. 2, Fig. 4 a transverse secv. tion on the dotted line in Fig. 2 of one side of the machine, and'Fig. 5 a detail view illustrating the money column more clearly.

In said drawings the portions marked A represent the frame of the machine, B money containing columns, and C a reciprocating carrier on which the push-bars and Voperating mechanism are mounted. The

frame A is preferably of metal and consists Specification of Letters Patent.

of appropriate side pieces supported on legs a and having a. top A1.\vl1icl1 is formed double, or hollow, for a purpose to be presently described, and with its forward end formed with pockets to receive the money columns B.

The money columns B are of the form vadapted to project through the slot in the money column receiving pocket, by which said coin retaining device may be removed from the coin holder after it has been put in position in the machine. Said coin holders are each provided with a follower 13 adapted to rest upon the top of the column of coins and havinga finger 11 projecting through the slot in the holder and in the pocket inthe frame, for a purpose to be presently described.

rlhe reciprocating carrier C is a plate of appropriate size and construction mounted in ways in the side pieces of the frame A and provided with a rack-bar 15 on its under side which engages with a pinion 16 mounted von a crankshaft 17, which is journaled in suitable bearings depending from said side pieces of said frame. Said crankshaftis provided with a handle 1S by which it is operated. A pivot shaft 19 is mounted in bearings 20 on the top of the carrier C and extends entirely across said carrier from side to side. A series of push bars 21, 22, 23, 24, 25, 26, 27, 2S, 29, 30, ai, and ae are mounted to rock on said pivot shaft, the forward ends extending to points adjacent to the money columns when in normal position, and their. rear ends extending backward a sufficient distance to be covered by the operating levers. f

A series Iof rectangular operating levers 33, 34, 35, 36, 37 as, 39, 4o, 41, 42, 43, and 44 are mounted on said pivot shaft 19, above the upper surfaces of said push bars. Each of said levers is in the form of a four-sided rectangular frame, and they are of varying sizes so that they can be nested or arranged one within the other in a series, as shown most clearly in Fig. 2. Each of said bars has a dependingear at each end,-

formed with a perforation through which the pivot shaft 19 extends. Each one ofthe push bars is formed with recesses in its upper side, adapted to receive the lower edges of `button, on its upper end on which is in` the rocking rectangular levers, except one, an upwardly extending lug 45 being formed between the recesses under one of said levers on each side of the pivot shaft Y19, which lugs serveto establish an operative bearing between said push rod and said lever. Thls construction will be best understood by an examination of Fig. 3, wherein push rod 27 is shown in elevation and the lever 38 is shown with its lower edge resting on the upper surface of the lugs 45 formed between the recesses in the upper edge of said push rod, which recesses are adapted to receive the lower edge of all the other levers when tilted in either direction and render said push rod inoperative by the tilting of said other levers. This arrangement continues throughout the mechanism, one of the levers being arranged vin a similar manner to operate, when tilted, one of the push rods to throw its outer end up or down, as the case may be.

`A series of selecting keys 46 are mounted on the lower ends of spring-mounted push rods 47 behind the pivot shaft 19, and another series of keys 48 are mounted on spring-mounted push rods 49 in front of said pivot shaft 19. Said push rods are of a common form, each having a head, or

scribed the denomination of the coin, or the sum of money which is y intended to control in connection with theoperation of the machine. A coiled spring 50 is interposed between a collar 51 on each of said push rods and the lower part of the hollow top of the casing, and operate to normally hold said keys in elevated position. In the arrangement of the keys 46 and 48, the faces,

which contact with the top edges of the levers beneath, are so formed by notching or recessing that those levers operated by forcing down `one key will operate to tilt into '35, 36, and38. These several levers will tilt push rods 27, y29, 30, 31, and 32, throwing the forward ends of said levers upward into posltlon so that the ejecting head 52 on the top of said push rods at their forward ends will be in position to pass through the slot in spring plate 53 beneath the several money columns indicated and eject a coin from each of said money columns, which will slide out over the curved outer edge of said support 53 and fall into a trough 54 with an inclined bottom and slide to the end thereof where it can be received by the user. The coins so discharged will aggre# gate the amount indicated Qn the button pushed. By forcing do-wn key 48 on the opposite side of pivot shaft 19, these several keys will be reset, inasmuch as key 48 will contact with the raised edge of the same levers that have been moved into operative position by the corresponding key 46. A spring catch 55 is positioned adjacentv to the Vend of each of the push rods and which cooperates with a projection 56 on said end and serves to hold the push rod at the extreme limit of one of its rocking movements. Other spring catches 57, mounted alongside said push bars near their forward ends, contact with projections on the side of said bars for the same purpose. It will be understood, of-course, that one set of said springs may be dispensed lwith ifl desired, and also that any other form of retaining ,device preferred and found appropriate may be substituted.

In the use of this machine it will be understood that the keys on the opposite sides of the rock-shaft 19. are intended to coperate to produce the desired result. 'It will also be noticed that the series of money columns consist of five columns for containing cents, four columns (5a, 5b, 51, and 52) for containing live-cent pieces, one column for containing ten-cent pieces, one column for containing twenty-live-cent pieces, and one column for containing fifty-cent pieces. It will be readily seen that with this combination of columns any sum from one cent tn one dollar can be selected. On the rear side of the rock-shaft the keys are numbered from 5 to 100 in successions of five-cent increases,which represent any sum of money likely to be tendered for the purchase, except the exact change.

On the opposite side, or on the forward side, of said rock-shaft are a series of keys 0, 1;2, 3, 4, for selecting the cent columns, and then from 5 to 95 arranged in successive increases of five cents each; also a key E or restoring the mechanism in case of error. The key E has its bar/portion 48 \formed with a straight-or unnotched edge Vextending across the several operating 1evers 33 to 44 on the rear side of the shaft 19, and is adapted, when depressed, to en gage all of said levers and thereby restore the push bars 21 to 32 to normal position.

Let us suppose, for example, that the amount of a purchaseis eighty cents, and

4that the purchaser tenders one dollar in payment. The operator first pushes d'own the key 100, which willset the push rods Lower set keys raise irz'ppers.

necessary to aggregate said sum of one dollar. He then pushes down the push key 80, -and alsopthe key 0, which will throw down, and outY of operative relation with the money columns, the keys necessary to aggregate the sum of eighty cents and also the cent keys. Then, by operating crank 18, the carriage C is runforward and the push rods remaining in operative position will throw, out twenty,cents in change, as one 'dime and two five-cent coins, which is the amount desired. Whenever an error occurs in setting the machine, by throrwing down key E, all of the levers are restored to normal position when they can be re-set and the error corrected.

The money combinations involved in the operation of themachine are the following:

Now, assuming that $1.00 has been tendered for an eighty cent purchase, the one dollar key is depressed and operates to raise the push bars aggregating that amount plus five cents (viz. 100:50-25-51--52--l 10-l1111-5b). r1`-he key designating 80 cents of the upper bank is then pushed, and also the zero (0) key, which operate to depress the push bars of the ldenominations totaling 85 cents (viz. :80-0:50- 25-51-11111.) These two operations then Upper Set keys depress trippers.

produce the following combinations: (keys In the bank of keys designated Amount dicating the amount of the sale, must be pushed when the purchase is five cents or any multiple thereof up to ninety-live cents. Thus the live cents is discounted in the transaction since the zero key designates 'five pennies, or the amount in excess..

Where the amount of a purchase is less than five cents, 'or greater than five cents and not a multiple thereof (e. g. 3, 4, 18, 23, 32,

or 97 cents), the Amount tendered keys are operated as before and the proper key or keys, to ythe amount purchased, of the and keys .#30 and #2 in the rear bank. 70 'y -The combinations involved are then as follows The push rods corresponding to 25 and 5, were not initially raised and therefore were ynot required to depress. The equation otherwise leaves a balance of eight cents or the correct amount of change to be delivered.

by the machine. Do not press O key when there are odd cents. Thus 47 :25- 5,-5,-10, and 2. i

In order to obtain the change from this machine in coins of the larger denominations, I have devised a special money combnation, by the use of which this result can be accomplished. Such a special money combination or system is necessary to secure the result stated, owing to the fact that our money system is not a common multiple system. For instance, change aggregating eighty cents would, bythe usual system, be delivered in nickels and dimes, but by the use of this machine, arranged and operated 85 in accordance with my system, such change would be delivered in fifty, twenty-live, and

five cent coins. This system is, in fact, in-

corporated in the formation and arrangement of the keys and mechanism, whereby o the particular push rods necessary to secure the change in the denominations desired are brought into operative relation with the coin columns.

I have shown a means for automatically indicating when the coin columns are eX- hausted, consisting of a rock-shaft 60, which is slightly offset or crank-shaped between its ends and adapted to contact with the lower end of a striker 61 which is adapted to strike an alarm bell 62 mounted -on a bracket 63 on the front end of the machine. A weighted striker 61 normally holds the offset or crank portion of the shaft in horizontal position. When the weight 85 13 reaches the bottomof the money column, its arm 14 strikes said crank portion of the shaft 60 and turns the head of striker 61 back from the bell 62. As the arm 14 passes said crank, the weight of the striker willl 0 cause it to fall forward and hit bell 62, an-

nouncing to the operator that one of the columns is empty, which can be readily Jascertained by viewing the front of the machine and noting the position of the projecting arms 14. This column is then lifted out and another, lled with the coins of the appropriate denomination, `placed in the -machine as before described, when it is thenA ready for further operation.

Having thus fully described my said invention, what I claim as new and desire to 8,5

secure by Letters Patent, is:
